The PVC insulated power cable can be made complying with standards: IEC, BS, DIN, CSA, NFC, ASTM, GOST, JIS etc.
The long-time working temperature of cable conductive core is not more than 70 centigrade
During short circuit(max. Permanent time is not more than 5 seconds), the max temperature of cable conductor is not more than 165 centigrade.
The different level of laying cable is not restricted. When laying the cable, ambient temperature is not lower than 0 centigrade.
They have good chemical stablility, and properties of acid resistance, alkali resistance, salt resistance, oil resistance, solvent resistance and flame resistance.
Light weight, good bending property and easy installation and maintenance
The conductor can be copper or aluminum, PVC insulation, PP filler, cable core wrapping tape, non-woven eloth wrapped inner bendding material layer, steel-wire armoured, steel-tape armoured, PVC or PE sheath power cable.
